Title: Ceramics circuit board
Inventor: TANAKA TADASHI
IPC: H01L23/373
Filed: 1988-04-25
Abstract: PURPOSE:To improve solder wettability of the surface of a copper circuit board by specifying the average roughness at the center line and the maximum surface roughness of the outer surface of the copper circuit board. CONSTITUTION:A copper circuit board shaped as desired or a flat copper plate is arranged on a ceramics substrate in contact therewith, and they are heated to a temperature lower than the melting point of copper and higher than the eutectic temperature of copper and oxygen so that the copper is bonded to the ceramics. Then a circuit pattern is formed on the copper plate by etching or the like. The outer surface of the copper circuit board should have a surface roughness of 3.0mum or less on average at the center line and a maximum surface roughness of 18.0mum or less. Since the surface roughness of the copper circuit board becomes larger approximately in proportion to increase of crystal grain size of copper, a copper material having appropriate crystal grain size must be used while heating and cooling conditions are controlled carefully. In this manner, it is possible to obtain a copper circuit board having surface roughness as desired.

IPC: F23L17/02
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To always suppress the occurrence of down-wash phenomenon regardless of a wind direction and an air velocity by a method wherein a plurality of louvers are erected at the periphery of the top part of a chimney to relive the occurrence of down-wash phenomenon of exhaust gas from a chimney.

Based on measuring results, a louver drive range is set by a calculator 13 and the height of a louver 2a in the range is set. When a control signal to an electric motor 7 from a controller 14 is outputted, each louver 2a is driven to a given height, based on the control signal. When, for example, an air velocity is lower than a given speed, the all louvers 2 are set to a maximum height by the controller 14. This constitution prevents the occurrence of down-wash phenomenon and keeps a state of smoke in an excellent state.

Title: Liquid crystal element
Inventor: NAKAMURA TOYOICHI
IPC: G02F1/133
Filed: 1988-04-27
Abstract: PURPOSE:To obtain a sufficient memory characteristic and high speed characteristic even if a liquid crystal has spontaneous polarization by forming a specific electrostatic capacity to the spontaneous polarization of the liquid crystal and changing the direction of the electric field to be impressed between the transparent electrodes of two sheets of substrates. CONSTITUTION:A transparent conductor layer 4 which sandwiches a dielectric layer 3 provided on the inner surface of the transparent electrode 2 of one substrate 1 together with the transparent electrode 2 is provided to form the electrostatic capacity of >=4A(nF/cm<2>) to the spontaneous polarization A(nC/cm<2>) of the liquid crystal, by which the direction of the electric field to be impressed between the transparent electrodes 2 and 8 of the two substrates is changed. Inversion takes place and the memory characteristic degrades when the reverse voltage impressed on the liquid crystal is larger than the inversion threshold voltage of the liquid crystal, but the reverse voltage is maintained small by sandwiching the transparent conductor layer 4 consisting of indium oxide with the dielectric layer 3 consisting of silicon dioxide to form the capacity and increasing the capacity in such a manner. The high-speed response liquid crystal element with which the large spontaneous polarization is effectively utilized is thereby obtd. without impairing the memory characteristic.
